IMPROVEMENT lN SCYTH E-FASTENINGS.

Specification forming partof Letters Patont No. 11.983. datcd November21, 1854.

To all 'whom it may conccm:

Be it known that I, 'THOMAS C. BALL, of Shelburne, county of Franklin,State of Mas sachusetts,have invented anew and improved mode of securingscythes upon their snaths for the purpose of using the same, and which Idenominate an improved Scythe-Fastening; and I do hereby declare thatthe following is a full and exact description thereof, reference beinghad to the accompanyin; drawings, and to the letters of reference markedthereon- Figure l being a perspectivc view, Fig. 2, a longitudinalelevation, and Fig. 3 a transverse section, ot a portion of the snathWith the fastening attached thereto.

A rep'resents the snath. B is a band or ferr'ule, ot' iron or othersuitable metal, having an extensiowplate, G,extended longitudinally uponthe face of the snath A. Through the fiattened face ot' thiseXtension-plate G there is formed laterally a dovetailcd recess orgroove, E, describing the arc ot' a circle having its center at or nearthe center, (shown at Gr.) To this recess E is fitted a slide, D, havingupon its onter face and firnly connected by` I, which passes through thesnath and is secured within the thumb-wheel H, by means of which the camG is made to revolve.

The mode of using or Operating the fastening is as follows: The shank Kbeing placed between the fulcrums F F, the slide D is placed in anyposition within the arc described bythe recess E which may be desired tocause the point ot' the scythe to remain at a greater or less distancefrom the operator. The thumbwheel H is then turned, thereby causing thecam G to revolve, andits greater diameter being extended against theshank, as at 75, a leverage is produced by the shank K between thefulcrums F F, thereby rnly securing the shank between the fulcrums, andalso by the said leverage securing the slide D in its position withinthe recess E, thus tirmly securing the scythe to the snath,to which thefastening is attached.

I do not confine myself to the use of a cam, nor to the precise form orarrangenent ot' the several parts as herein set forth, but shall varythe same while I attain the same end by the several parts, as hereindescribed, or their mechanical equivalents.

I do not claim the using of a cam or eccentrio for confining a scythe,nor the band and extension-mate attached; but

What I do claim as my invention, and desire to secure by Letters Patent,is-

The slide D, With its fulcruns F F and its corresponding recess, E, inconnection with the leverage ot' the shani: K, substantially as setforth.
